Title: Revolving method on concrete surface, and revolving cutter therefor
Inventor: TAKAHASHI MITSUO
IPC: E01C23/09
Filed: 1995-06-16
Abstract: PURPOSE: To prevent dust from occurring on execution of works for providing nonskid surface, and to shorten term of works by a method wherein a number of paralleled grooves are formed with a revolving cutter on the surface of damp-dried concrete. CONSTITUTION: A revolving method is composed of a concrete-placing process, a vacuum treatment process for making the placed concrete damp-dry in a short period of time by means of vacuum treatment, and a groove-cutting process for cutting grooves with a revolving cutter. After concrete is placed, the vacuum treatment is applied, and grooves are cut on the surface 20 of damp-dried concrete with a revolving cutter 10 made to travel on the concrete surface. The grooves 21, cut by the above- mentioned processes, are formed in smooth finishing with their upper edges sharpened. As the grooves 21 are provided lengthwise and breadthwise with the surface thereof made up in stone pavement-like appearances, specific finishing becomes unnecessary.  As the revolving cutter 10 is so constructed that each of revolving cutter edges 12 can rotate independently, cutting can be executed efficiently, even though some of the revolving cutter edges get out of order, without interrupting rotation of the remaining revolving cutter edges.
